DescriptionBACKGROUND OF THE INVENTION
This invention relates to an electronic fencing toy or game, and more particularly, to a toy or game of the type wherein two fencing figures are controlled by opposing players and moved to engage in a fencing duel.
Over the years there have been a number of toys or games wherein two figures are controlled by the respective players in a manner simulating a fight or boxing match. Typical of such prior art arrangements is Breslow U.S. Pat. No. 3,864,870wherein two figures are mounted for movement relative to each other, each having an actuator which can be manipulated by the player to cause their figure to fight with the opposing figure. If a target area on the opposing figure is struck by theactuator of the other figure a latch is tripped so that the figure which has been struck moves from an upright to a prone position thereby signalling the end of the fight. In the boxing toy or game disclosed in Glass et al U.S. Pat. No. 3,235,259 twoboxing figures may be manipulated by the opposing players and when one figure is struck in a particular manner the losing fighter's head pops up, and a noisemaker produces an appropriate sound. Other boxing or fighting toys or games are shown, forexample, in Goldfarb et al U.S. Pat. No. 3,845,956, Fletcher U.S. Pat. No. 3,106,800, Crowell U.S. Pat. No. 1,799,735, Carlson U.S. Pat. No. 2,393,289, Gilchrist U.S. Pat. No. 1,447,976, McIntosh U.S. Pat. No. 1,745,434, Davis U.S. Pat. No.2,269,095, Armstrong U.S. Pat. No. 2,716,840 and Austrian Pat. No. 96,176.
SUMMARY OF THE INVENTION
It is a principal object of the present invention to provide a new and improved fencing toy or game wherein two fencing figures are mounted for controlled movement by the players to simulate a fencing duel.
It is another object of the present invention to provide a new and improved toy or game wherein two movably mounted fencing figures are provided with electrically conductive swords and facilities are provided for developing a unique audiblesignal during periods when the swords are in electrical contact with each other.
It is a further object of the present invention to provide a new and improved fencing toy or game wherein the audible signal decays in amplitude after disengagement of the conductive swords at a relatively gradual rate to provide an echo orethereal effect for the audible signal.
It is another object of the present invention to provide a new and improved fencing toy or game wherein the audible signal produced upon engagement of the conductive swords of the fencing figures is developed by frequency modulating two differenttone signals with a low frequency pulse type signal, the modulated tone signals then being combined to provide a composite sword touch tone signal which is produced each time the swords touch.
It is another object of the present invention to provide a new and improved fencing toy or game wherein a conductive target area is provided on each of the fencing figures and facilities are provided responsive to the engagement of the conductivesword tip of either figure with the target area of the other figure for developing both an audible and visual signal indicating that a hit has been scored on the opponent.
It is a further object of the present invention to provide an arrangement wherein facilities are provided responsive to a hit on the target area of the opposing figure for disabling the development of further audible signals in response to swordengagement.
It is another object of the present invention to provide a new and improved fencing toy or game wherein facilities are provided responsive to a hit on the conductive target area of the opposing figure for preventing the struck figure fromthereafter causing a hit upon his opponent.
It is another object of the present invention to provide a new and improved fencing toy or game wherein facilities are provided for resetting the visual and audible generating means in response to movement of the figures to spaced apart locationsso that another duel may be initiated.
Briefly considered, the arrangement of the present invention achieves the foregoing objects in a structure including a base member having two fencing figures mounted thereon for movement relative to the base and each other so that the conductivesword carried by each figure may be engaged one with the other and the figures manipulated so that the conductive sword of one figure may touch the conductive target area of the other figure, and vice versa. Preferably, the figures are in the form ofrobots from outer space and when the conductive swords of the robot figures touch a unique audible signal is produced which is in the motif of the popular concept of outer space sounds and simulates the swishing and swooshing character of a sword blademoving through the air. When the swords are separated this audible signal dies out slowly so as to give an echo or ethereal effect thereto. If the conductive sword tip of one figure is maneuvered to engage the conductive target area of the other figurea unique sound signal is generated and a corresponding portion of the figure is illuminated by a flashing light. These audible and visual indicating signals are continued until the fencing figures are removed to remote locations at which point theaudible and visual indicating signals are terminated. After a hit has been made by one figure, facilities are provided for preventing the development of sword touch sounds after the hit and prior to the separation of the figures to their remotelocations. Also, after a hit has been made by one figure, facilities are provided for preventing the other figure from thereafter producing a hit upon his opponent.
Other objects and advantages will become apparent from the following description taken in connection with the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENT
Considering first the mechanical aspects of the fencing toy or game of the present invention, and referring particularly to FIGS. 1 to 5, inclusive, a base member 10 is provided having a longitudinally extending slot 12 in the upper surfacethereof within which slot a pair of fencing figures 14 and 16 indicated generally at 14 and 16 are mounted for movement relative to each other and the base member 10. Each of the fencing figures 14, 16 is provided with a handle 18 by means of which thefencing figure may be moved along the length of the slot 12 and upon movement of the handle 18 to left or right the corresponding fencing figure is rotated about a vertical axis. In addition, up and down movement of the handle 18 is employed to producecorresponding up and down motion of a conductive sword portion 20 of the fencing figure. More particularly, each of the fencing figures 14, 16 includes an outer housing or body portion indicated generally at 22 and a centrally located post portion 24,the bottom end of the post 24 being connected to a circular disc 26 the edges of which ride on the upper surface of the top wall 28 of the base member 10. In the illustrated embodiment the body portions 22 of the figures 14, 16 are in the form of robotsfrom outer space, although any suitable design for these figures may be employed insofar as the present invention is concerned.
A rectangular plate 30 is slidably mounted in the groove formed in the base member 10 by the top wall 28 thereof and a trough shaped lower wall 32 of the base member 10, the bottom end of the post 24 being rotatably mounted in the plate 30 bymeans of the screw 34 and washer 36 which retains the post 24 connected to the plate 30 while permitting rotation of the post 24 relative thereto.
The handle 18 of each fencing figure is provided with a pair of opposed end portions or fingers 38, 40 which are positioned on either side of a flat portion 42 of the center post 24. The handle 18 is pivotally mounted to the post 24 by means ofthe pin 44 which extends through the fingers 38, 40 and the post portion 42.
The conductive sword 20 of each fencing figure comprises an electrically conductive flexible coil of wire 46 one end of which is mounted in a centrally located hub portion 48 of an arcuately shaped plastic plate member 50, the portion 48 andplate 50 simulating the hilt or guard of a conventional sword. In order to rotate the sword 20 about a horizontal axis the plate 50 is provided with a pair of rearwardly extending arm portions 52, 54 which are pivotally mounted on a pin 56 which issupported between the opposed arms 58, 60 of a support assembly 62 secured to the central post 24. Preferably the assembly 62 may be formed with the post 24 in a one-piece molding operation.
In order to control rotation of the sword 20 about the pin 56 in accordance with up and down movement of the handle 18 about the pin 44, the arms 52, 54 are provided with offset extensions 52a, 54a between which is positioned the end portion 64of an interconnecting link indicated generally at 66, the other end of the link 66 terminating in the parallel arms 68, 70 which are connected to the arms 38, 40 of the handle 18 by means of the pin 72. The arms 52a, 54a are positioned on either side ofthe upper end 64 of the link 66 and connected thereto by means of the pin 55.
With the manipulating arrangement described thus far, each of the fencing figures 14, 16 with its conductive sword 20 may be moved along the slot 12 by pushing or pulling on the handle 18, each figure may be rotated about the axis of the post 24by rotation of the handle 18 about this vertical axis and the sword 20 of each figure may be pivoted about the horizontal axis of the pin 56 by corresponding pivotal movement of the handle 18 relative to the post 24. In this connection it will be notedthat movement of the handle 18 produces movement of the sword 20 in the same direction due to the inverting connection of the link 66 between these members.
In the illustrated embodiment, each of the housing or body portions 22 of the fencing figures are arranged to simulate a robot type of fencing figure. Thus, each housing includes a transparent face mask portion 80 and a translucent helmetportion 82. The body 84 of each figure includes integral arm portions 86 in the ends of which the pin 56 is secured so that the body 22 rotates with the post 24 when the handle 18 is rotated. Also, the body 22 is centered at the upper end thereof bymeans of a disc-shaped member 88 which is provided with a central opening for receiving the upper end 90 of the post 24. The outer edge of the member 88 rests on the upper edge of the body portion 84 so that the fencing figure is centrally located withrespect to the upper end of the post 24, the body portion 84 extending downwardly to the surface of the disc 26 so as to enclose the above-described mechanism for rotating the sword 20. One side of the body portion 84 is provided with an opening 92 topermit pivotal movement of the handle 18 relative to the post 24 and the other side of the body 84 is provided with the slot 94 to permit movement of the link 66 as the sword 20 is moved in response to pivotal movement of the handle 18.
Each of the fencing figures is provided with an opening 96 in the body portion 80 on the side facing the opposing figure and a conductive plate 98 is secured in place behind the opening 96 by any suitable means. If desired a second target areamay be provided on each figure, as indicated generally at 97 in FIG. 2, this area also containing a conductive target plate which may be electrically connected to the plate 98. Each of the conductive swords 20 of the fencing figures is provided with aconductive tip portion 100 and the control circuit of the fencing game is arranged so that whenever the conductive tip portion 100 of the fencing figure makes electrical contact with the target 98 (or the target 97) an indicator lamp 102, which maycomprise a number 47 pilot light, is illuminated to indicate that a hit on the opposing figure has been made. The indicator lamp 102 is mounted in an electrical socket provided in the upper end portion 90 of the post 24 of each figure, the member 88acting as a reflector for the lamp 102. When the lamp 102 is illuminated, light from this lamp passes through the transparent dome portion 80 to indicate to the players that a hit has been made. Preferably the transparent portions 80 of each figure areof different colors, such as red and blue. In addition, when a hit is made on the target area 98 of the opposing figure an audible sound is produced, as will be described in more detail hereinafter.
Before considering the circuit arrangement of the present invention, which is shown in FIG. 6, it is pointed out that one of the fencing figures, such as the figure 16, has the conductive tip portion 100 of its sword 20 electrically insulatedfrom the outer end of the electrically conductive coil of wire 46 which forms the flexible shaft portion of the sword 20. More particularly, as shown in FIG. 2, an insulating sleeve 106 is secured to the outer end of the flexible coil 46 and theconductive tip portion 100 is secured to the outer surface of the sleeve 106 by any suitable means. In the fencing figure 16 separate wires 108 and 110 are connected respectively to the end of the coil 46 and the conductive tip portion 100. The wire110 is insulated and its conductive end portion 112 is connected to the conductive tip portion as indicated by the connection 114, the insulated wire 110 extending back through the center of the coil 46. The wire 108 is connected to the inner end of thecoil 46 as indicated by the connection 116. In the other fencing figure 14, the insulating sleeve 106 is eliminated and the conductive tip portion 100 is electrically connected to the outer end of the coil 46. Accordingly, in the fencing figure 14,only the single wire 108 is required to make an electrical connection to the coil 46 and the tip 100.
Considering now the circuit arrangement of the present invention shown in FIG. 6, a low voltage supply potential indicated by the symbol Vcc is provided by the batteries 120 and this supply potential is connected to the control circuit ofthe invention through the ON OFF switch 122. A first tone signal, which preferably has a frequency of 1.1 KHz is developed by a phase shift oscillator which includes the inverting amplifiers 124 and 126 which form a part of an integrated circuit chipwhich is preferably of the commercial type 4069, the pin connections for this chip being shown in FIG. 6. The output of the amplifier 126 is connected through the feedback capacitor 128 and the resistor 130 to the input of the amplifier 124. Thiscapacitor is also connected to the resistor 132 to the input of the amplifier 126 so that a sufficient phase shift is provided to produce sustained oscillations at a frequency of 1.1 KHz at the junction of the capacitor 128 and the resistor 132. Asimilar tone generator, comprising the amplifiers 134 and 136 on the type 4069 chip, the capacitor 138, and the resistors 140 and 142 is provided to generate a tone signal having preferably a frequency of 750 Hz. A third pulse type oscillator isprovided by the amplifiers 144 and 146 on the type 4069 chip, the capacitor 148, and the resistors 150 and 152, this third oscillator providing an output of seven pulses per second. The output of this third oscillator is employed to frequency modulateboth of the tone signals developed by the first two oscillators. More particularly, the seven p.p.s. output of the third oscillator is supplied through a diode 154 to the input of the amplifier 124 and through the diode 156 to the input of theamplifier 134.
The frequency modulated outputs of the two tone generators are combined by means of the diodes 158 and 160 which are connected to the input of a non-inverting buffer section comprising the AND gates 162 and 164. The stages 162 and 164 preferablyform a part of an intergrated circuit of the commercial type 74C08, the terminal connections for these AND gates being shown in the drawing. The gates 162, 164 provide some degree of limiting which, together with the frequency modulation components ofthe two frequency modulated tone signals which are combined and mixed in these gates, produces a unique composite sword touch tone signal of a swishing and swooshing nature which is in the nature of the popular concept of outer space sounds and to acertain extent simulates a sword blade moving through the air. The output of the buffer section 162, 164 is supplied through a relatively large capacitor 170 to the base input of a two-stage Darlington amplifier 172. The output collector of theDarlington amplifier 172 is connected through a loudspeaker 176 to the supply potential Vcc, the emitter electrode of the output stage of the Darlington amplifier 172 being connected to ground. In the absence of an enabling bias on the base inputof the Darlington amplifier 172, this amplifier in nonconductive and hence does not transmit the composite sword touch tone signal to the loudspeaker 176. However, the coil spring 46 of the conductive sword 20 of one of the fencing figures, i.e., thefigure 16, is connected through a resistor 182 to the base input of the Darlington amplifier 172. The supply potential Vcc is connected to the conductive coil 46 of the sword of the other fencing figure 14, as shown in FIG. 6, it being recalledthat the conductive tip portion 100 of the figure 14 is also conductively connected to the end of the conductive coil 46, as shown diagrammatically in FIG. 6. When either the coil portion 46 or the tip portion 100 of the fencing figure 14 makeselectrical contact with the coil 46 of the opposite fencing figure 16, the supply potential Vcc is supplied through the resistor 182 to the base input of the amplifier 172 so as to enable this amplifier to supply an amplified composite sword touchtone signal to the loudspeaker 176. The Darlington amplifier 172 is thus turned on rapidly to provide a sharp attack time for the composite sword touch tone signal.
In accordance with an important aspect of the invention, facilities are provided so that the sword touch tone signal decays slowly when the swords of the two figures 14, 16 are separated. During this decay, the seven-pulse-per-second frequencymodulation components of the composite tone signal give an apparent echo or ethereal effect as the composite signal dies out. The envelope 173 of the composite sword touch tone signal is shown in FIG. 7. More particularly, when the swords touch and thesupply potential is connected to the resistor 182, the large capacitor 170 is charged rapidly through the resistor 182 as shown by the leading edge 171 of the envelope 173 of FIG. 7. However, when the swords separate and a supply potential is no longerconnected to the resistor 182, the capacitor 170 must discharge slowly through the high input impedance of the Darlington amplifier 172. Acccordingly, the amplitude of the composite tone signal decays slowly after the swords are separated, as shown bythe decay portion 175 of the envelope 173 in FIG. 7, to provide the above-described echo effect in which the swooshing sounds of the frequency modulation components of the two tone signals are quite pronounced.
As discussed generally heretofore, when the conductive target area 98 of one of the figures is touched by the sword tip portion 100 of the opposing figure one of the tone signals developed by the above-described oscillators may be selectivelysupplied to the loudspeaker 176 to provide an audible indication that a hit has been made by one of the fencers. Furthermore, since the tone signals are distinguishable by their frequencies, an indicating means is provided whereby each player isimmediately informed as to which player has made a hit while employing only the single loudspeaker 176 as the audible indicating means.
More particularly, when the target 98 of the figure 16 is electrically engaged by the sword tip portion 100 of the opposite figure 14, an enabling signal is supplied to one input of a NOR-gate 190, it being recalled that the sword tip portions100 of both figures are connected to the supply potential Vcc, as shown in FIG. 6. The NOR-gate 190, together with a NOR-gate 192, forms an RS latch which is set when the supply potential Vcc is connected to the target 98 as described above,these gates preferably forming a part of an integrated circuit chip of the commercial type 74C02. The NOR-gates 190 and 192 are cross connected in a conventional latch arrangement so that when the Vcc potential is applied to the target 98 theoutput of the NOR-gate 192 goes from a low to a high potential and the output of the NOR-gate 190 goes from a high to a low potential. The output of NOR-gate 192 is supplied to one input of an AND gate 196, which may be on the same type 74C08 chip asthe AND gates 162, 164, the other input of the AND gate 196 being connected to the frequency modulated tone signal output of the 750 cycle tone oscillator. The output of the AND gate 196 is supplied through a resistor 200 to the input of a Darlingtonamplifier 202 the output of which is connected to the loudspeaker 176. Accordingly, when the target 98 of the figure 16 is hit the latch 190, 192 is set, the gate 196 is enabled, and the 750 cycle tone signal is amplified in the amplifier 202 andsupplied to the loudspeaker 176. The output of the AND gate 196 is also connected through a resistor 204 to the input of a Darlington amplifier 206 in the output of which is connected the pilot lamp 102. Accordingly, when the target area 98 of thefigure 16 is hit, a visual signal is also produced by energization of its lamp 102. Since the tone signal supplied to the amplifier 206 is frequency modulated by the seven-pulse-per-second modulating signal, the visual indication provided by the lamp102 is a flashing light which is visible through the transparent dome 80 of the figure 16.
In an entirely similar manner, the NOR-gates 208 and 210, which are on the same type 74C02 chip as the gates 190, 192, provide a latch which is set when the target 98 of the figure 14 is hit, the output of the NOR-gate 210 being supplied to oneinput of the AND gate 214 (on the type 74C08 chip) to the other input of which is supplied the 1.1 Kc frequency modulated tone signal. Accordingly, when the target 98 of the figure 14 is hit, the AND gate 214 is enabled and the corresponding tone signalis supplied through the resistor 216 to the amplifier 202 wherein it is amplified and supplied to the loudspeaker 176. The output of the AND gate 214 is also connected through the resistor 218 to a Darlington amplifier 220 which controls energization ofthe pilot light 102 of the figure 14, so that a flashing light signal is developed by the lamp 102 of the figure 14 when its target 98 is hit.
As soon as one of the latches 190, 192 or 208, 210 has been set in the manner described above, the corresponding tone signal will continue to be supplied to the loudspeaker 176 and will energize the corresponding one of the indicator lamps 102until the latch is reset. In accordance with a further feature of the invention, these latch circuits are reset by moving the fencing figures apart to predetermined locations along the slot 12. More particularly, the reset switches 222 and 224 areprovided at either end of the slot 12 and may be mounted in the bottom wall of the trough 32, as shown in FIG. 2. The plate 30 of each figure is provided with a depending portion 226 which has an inclined surface 228 which is adapted to engage thebutton of one of the switches 222 or 224 when the figure is moved to the end of the slot 12. When the reset switch 222 is closed it connects the supply potential Vcc to the reset terminal of the latch 190, 192 so that this latch is returned to itsinitial condition. In a similar manner, the reset switch 224 resets the latch 208, 210 when it is closed. When the latch circuit is reset, the enabling potential is removed from the input of the AND gate 196 or the AND gate 214 so that the tone signalis no longer supplied to the loudspeaker 176 and the indicator lamp 102 is no longer energized.
In order to prevent any further sword play after a hit has been made on the target area of one of the figures, the sword touch tone signal is disabled when one of the latches 190, 192 or 208, 210 is set. More particularly, the output of theNOR-gate 208 is supplied through a diode 230 to the input of the amplifier 172 and the output of the NOR-gate 190 is connected through the diode 232 to the input of the amplifier 172. Normally, the outputs of the NOR-gate 190 and 208 are at a highpotential and hence do not affect the operation of the amplifier 172. However, when either one of the latches 190, 192 or 208, 210 is set, a negative bias signal is supplied through the diode 230 or the diode 232 to the input of the amplifier 172 toprevent this amplifier from responding to the composite sword touch tone signal coupled to this amplifier through the capacitor 170. As soon as the fencing figures are moved apart and the latch is reset to its initial condition, the disabling biasingpotential is removed from the input of the amplifier 172 so that this amplifier may thereafter respond to a composite sword touch tone signal when the swords of the two figures are next engaged, as described in detail heretofore.
In accordance with a further feature of the invention, there is provided means responsive to a hit by either player for locking out the target latch circuit of the other player to prevent the player who has just been hit (who is "dead") fromrapidly scoring on his opponent, either on purpose or inadvertently, until after the player has caused his reset switch to be actuated. More particularly, a resistor 236 is connected from the output of the NOR-gate 192 to one of the inputs of theNOR-gate 210 in the opposing latch circuit, this input being connected to ground through the resistor 237. Similarly, a resistor 238 is connected from the output of the NOR-gate 210 to one of the inputs of the NOR-gate 192, this input being connected toground through the resistor 239. When, for example, the latch 190, 192 is set, the high output of the gate 192 is supplied through the resistor 236 to the reset terminal of the latch 208, 210 and holds the latch 208, 210 in its initial condition eventhough the target 98 is hit and the Vcc potential is supplied to the input of the gate 208. The latch 208, 210 acts in a similar manner through the resistor 238 on the latch 190, 192.
